HX711 Dual-Channel 24 Bit Precision A/D weight Pressure Sensor
HX711 is an electronic scale module, whose working principle is to convert the measured changes in resistance value changes, through the conversion circuit into electrical output. Amazingly cheap load cell amplifier HX711 module for a 24-bit A/D conversion with a 20mV scale. The board is just an ADC convertor and will work with any load cell The HX711 sensor module uses a two-wire interface (Clock and Data) for communication. Any microcontroller’s GPIO pins should work and numerous libraries have been written making it easy to read data from the HX711. Check the hookup guide on pictures for more information Application: HX711 DUAL-CHANNEL WEIGHING SENSOR MODULE is Widely used in aerospace, mechanical, electrical, chemical, construction, medicine, and many other fields, used to measure force, pressure, displacement, strain, torque, acceleration Getting some excellent, clear measurements from this chip. They’re quite easy to set up. Tags, HX711 Load Cell Amplifier Module, HX711 Dual-Channel 24 Bit Precision A/D weight Pressure Sensor, load cell amplifier module
